The multi-tenant houses of Nirankari Colony keep their overhead tanks on the roof and out of mind, and near the Yamuna belt sediment settles in steadily. KaamGenie drains, de-sludges and disinfects these rooftop tanks so forgotten tanks stop tainting the water. From ₹699.
Nirankari Colony is a settled residential pocket of independent houses and floors near the Yamuna in North Delhi. Water arrives through DJB lines, and each home stores it in an overhead rooftop tank, often one shared across a multi-tenant house. The colony's proximity to the river belt means a little extra silt hangs in the local air, and it settles into open tanks over time. On a still tank that grit drops to the floor as a fine sediment across the months. Because many of these houses hold several tenants, the rooftop tank rarely has a single caretaker, so it is easy to forget between cleanings. Ageing tanks with rougher inner surfaces also hold biofilm along the walls. Left alone, the deposits accumulate until the water clouds or the taste turns flat.
KaamGenie cleans these rooftop tanks the proper way: drain the tank down, scoop out the sludge, jet-wash the walls, then hand-scrub the corners and inlet where biofilm gathers. A anti-bacterial disinfectant wash goes in before we refill, and before-and-after photos reach your WhatsApp. This is our dedicated page for water tank cleaning in Nirankari Colony, focused on the overhead (rooftop) tanks these multi-tenant homes depend on. For a shared tank we coordinate with the tenants so the cost splits cleanly.
When a rooftop tank serves several tenants in one house, no single person feels responsible for climbing up to clean it, so it quietly goes a year or more untouched. Meanwhile it fills and drains daily on DJB supply, and the extra silt near the river belt settles on the floor each still night. Ageing tanks give that sediment and the biofilm a rough surface to gather on.
A forgotten tank keeps stirring its settled sludge back into supply every time it refills, so the water carries grit even soon after a top-up. Because the tank serves several households, that quality issue affects everyone at once. One coordinated annual clean is the sensible fix, and it splits neatly across the tenants who share the tank.
No travel charge anywhere in Nirankari Colony. The final price is confirmed on the call before we come — it depends only on tank size and access.

“Our house has tenants sharing one tank, can you coordinate?” Yes. We deal with whoever books us and set the day so all the tenants have supply back the same evening. A shared 1,001 to 2,000 litre rooftop tank is ₹1,299 to ₹1,499, and the tenants can split it. One before-and-after WhatsApp goes to everyone.
“Does being near the Yamuna make the tank dirtier?” The river belt adds a little extra silt to the local air, and that settles into open rooftop tanks over the months as a fine floor layer. It does not spoil the piped DJB water, but it does mean the tank needs opening and cleaning on a steady cycle.
“How do I tell if a forgotten tank needs cleaning?” If it has not been opened in over a year, if the morning water clouds, or if the taste has flattened, it is due. A multi-tenant tank that no one has been looking after is almost always overdue.
“What does it cost for a single-family rooftop tank?” A standard 500 to 1,000 litre tank starts at ₹699 and up to ₹899. Only larger or shared tanks move into the ₹1,299 to ₹1,499 bracket. We confirm the size on site.
“Will one clean fix cloudy water for good?” One full clean clears the current sediment and biofilm, and the water runs clear straight after. To keep it that way, an annual clean stops the tank ever building a thick layer again, especially with the river-belt silt here.
